Description

Electric vehicle charging apparatus for mechanical parking station

The present invention relates to an electric vehicle charging system for a mechanical parking lot, which can be charged simultaneously with parking in a mechanical parking lot.

Demand for automobiles is showing an explosive increase in accordance with economic development, and exhaust gas emitted from automobiles is a major cause of environmental pollution as demand for automobiles increases. This is due to the fact that fossil fuels such as gasoline, gas and gas are used as the main raw materials for automobiles to date.

Accordingly, there is a demand for reducing exhaust gas of automobiles, and research and development of automobiles capable of reducing exhaust gas are in progress. Furthermore, commercialization of electric vehicles that do not generate exhaust gas has been partially attempted.

An electric vehicle refers to a vehicle that operates using electricity as a source of driving power, and refers to a vehicle that mounts a battery that can be charged as a power supply source in the vehicle itself, and operates using power supplied from the mounted battery. Accordingly, an electric vehicle is largely driven by electricity to operate an electric vehicle, and a battery that supplies electricity to the electric motor is used as essential components.

In order for such a non-polluting electric vehicle to replace an existing fossil fuel-based vehicle, development in many technical fields is still required. For example, it is a reality that an electric vehicle is also required to have the ability to replace existing automobiles, such as an increase in battery usage time, that is, capacity, and capacity of an electric motor.

In addition to such technical problems, as a factor that hinders the spread of electric vehicles, charging systems for charging electric vehicles have not yet been widely distributed, so even when electric vehicles are purchased, it is difficult to find facilities such as charging stations for charging them.

Therefore, unlike gasoline, electricity can also be supplied by ordinary homes or buildings, so charging during parking is possible by installing a charging system in the parking lot of ordinary homes or buildings, and in the case of utilizing this, the lack of infrastructure such as a charging station is eliminated. It will be able to replace some parts.

In particular, in recent years, various types of parking facilities have been installed and operated to solve the parking problem caused by the increase in vehicles in the city, so if a charging system for charging electric vehicles is provided in these parking facilities, a separate infrastructure for charging electric vehicles In addition to making up for the shortage, it will be possible to further expand the spread of electric vehicles by improving the convenience of using electric vehicles.

However, electric vehicle charging facilities that have been generally distributed so far only supply general chargers that charge electricity from the ground, but there is no electric vehicle charging device for mechanical parking lots that can easily charge electric vehicles parked in an elevator-type mechanical parking lot. there is a problem.

The second one side cover moving part 812-1 includes a hydraulic cylinder 880 fixed outside the connection terminal body 802, a piston rod 882 extended by the hydraulic cylinder 880, and the piston rod It includes a rear end 884 of one half cover 808 connected to the end of 882.

When the hydraulic cylinder 880 is operated, the piston rod 882 is extended and one half cover 808 is moved from the upper portion of the connection terminal body 802.

The second cover moving part 814-1 is also a hydraulic cylinder 880-1 fixed outside the connection terminal body 802, and a piston rod 882-1 extended by the hydraulic cylinder 880-1. ), and a rear end portion 884-1 of the other half cover 810 connected to the end end of the piston rod 882-1.

When the hydraulic cylinder 880-1 is operated, the piston rod 882-1 is elongated and the other half cover 810 is moved from the top of the connection terminal body 802.

The air injection unit 870 for injecting air to the connection terminal plate 844 includes a driving unit 886 such as a motor fixed outside the connection terminal body 802, and a connection terminal rotating fan rotated by the driving unit 886 888 and a connection terminal nozzle part 889 formed to transmit the flow of air generated from the connection terminal rotating fan 888.

When the driving part 886 operates the connection terminal rotating fan 888, air that is moved by the connection terminal rotating fan 888 is transmitted to the upper surface of the connection terminal plate 844 through a nozzle, and is transferred to the connection terminal plate 844 surface. It acts to remove foreign substances attached to it.

Through this, even when foreign substances are attached to the connection terminal plate 844, the effect of being easily removed is generated.

10 is a schematic perspective view of a main part showing a connection process between a connection terminal part and a charging terminal.

In FIG. 10, the electric vehicle 101 is omitted and only the charging terminal 103 of the electric vehicle 101 is illustrated in FIG. 10, and the pallet 10 is omitted and only the connection terminal body 802 of the pallet 10 is illustrated.

In the present invention, as shown in (a) of FIG. 10, the outer sensor 862 of FIG. 7 operates independently to detect the position of the charging terminal 103, or the outer sensor 862 and the charging terminal 103 When the transmitting/receiving sensor 864 is operated to detect the position of the charging terminal 103, and the body moving part 806 is operated to move the connection terminal body 802 to the lower portion of the charging terminal 103, the charging terminal 103 ), the connection terminal body 802 of the pallet 10 is located.

In this state, the cover opening step as shown in (b) of FIG. 10 is to open the lower cover 866 of the charging terminal 103 downward, and one cover 867 and the other cover 868 of the connection terminal body 802 Open to both sides.

In the state as in (b) of FIG. 10, the step of correcting the position of the terminal as in (c) of FIG. 10 is performed using the plurality of inner sensors 824 as shown in FIG. ) Is operated to adjust the connection terminal plate 844 to be positioned at the correct bottom of the charging terminal 103.

In addition, the charging start step as shown in FIG. 10D extends the extension member 842 so that the connection terminal plate 844 comes into close contact with the charging terminal 103.

The present invention relates to a first step in which the connection terminal body 802 is moved to various positions of the charging terminal 103 formed under the electric vehicle 101, and after the first step, a connection terminal plate ( Through the second step of adjusting the 844 to be positioned in the correct lower part of the charging terminal 103, the effect of a precise charging process is generated.

The embodiments in the description of the present invention described above are presented by selecting the most preferable examples to aid the understanding of those skilled in the art from among various possible examples, and the technical idea of the present invention is not necessarily limited or limited only by this embodiment. , Various changes and modifications, and other equivalent embodiments are possible within the scope of the technical spirit of the present invention.
